PAPER TWINE FOR USE UPON GRAIN-BINDING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 451,773, dated May 5,1891. Application filed October 28, 1889. Serial No. 328,386.(Specimens) T all whom, it may concern:

Be it known that I, GEORGE L. RICE, of Ohicago, in the county of Cookand State of Illinois, have invented an Improved Paper Twine for Useupon Grain-Binding Machinery, of

which the following is a description, reference being had to theaccompanying drawings.

The object of my invention is to produce a twine from paper of suitablelength, thickness, and flexibility for use upon automatic grainbindingand other kindred machinery.

It consists of a central core made from a strip of paper of suitablewidth twisted into a twine and having a covering made from a I 5 similarstrip of paper, which is twisted around the said core.

Figure 1 is a perspective view of such twine partially made. Fig. 2 is aperspective view of the twine in its last stages of manufacture.

Fig. 3 is an enlarged section of the completed twine.

A is the strip of paper which forms the central core. I preferably formit first into a tube, as at a, commencing by turning or fold- 2 5 ingone edge inward, and then twist it, as at a, forming at that place acollapsed tube closely twisted.

B is the strip of paper, of suitable width and thickness,which forms thecovering of the twine. I preferably form this strip also into a tube,through which the core runs, and twist it in the same manner as abovedescribed.

The twine thus formed is superior to a twine made from one strip ofpaper having the aggregate width of the two strips above described,because the tubes at a and b, having thinner walls, collapse more easilyand are capable of being twisted more closely. The result is that such atwine has greater flexibility and a smaller diameter than if formed inany other manner. It is neither necessary nor possible that the twineshould always assume exactly the shape as shown in Fig. 3, because anyslight irregularity in the paper will cause the flutings consequent tothe collapsing of the walls to vary in number.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is-

1. As a new article of manufacture,a twine consisting of a central coreof papp g twine and an outer covering formed from a strip of paper, thetwo twisted together with one in side the other, substantially as andfor the purpose described.

2. A twine consisting of a central core and its covering twistedtogether, the core consisting of a twisted tube formed from a paperstrip, and the covering consisting of a paper strip applied in tubularform around the core.
